D VID GABRIELSEN ATTORNEY United States Patent 3,220,126 MULTISENSORYINTELLIGENCE TRANSMISSION DEVICES David Gabrielsen, North Tarrytown,N.Y., assignor to Soho-Libra, Inc., North Tarrytown, N.Y., a corporationof New York Filed May 4, 1960, Ser. No. 26,862 4 Claims. (Cl. 40-283)This invention relates to multi-sensory intelligence transmission, andparticularly to a novel and improved construction for effecting thepresentation of visual media in synchronism with related aurallyreproduced sound.

Multi-sensory intelligence transmission devices for effecting thesynchronous presentation of visual media with related aurally reproducedsound, such as motion pictures, film strips, slide and rear projectiondevices, are in widespread use today in many fields whereincomprehension of transmitted intelligence is facilitated by exposure ofa plurality of the recipients senses thereto. Such devices as thosementioned above which are in common use, usually require a darkened roomand special projection screens for visually effective presentationpurposes. Additionally, they are relatively expensive and of acumbersome and complicated nature that is oftentimes beyond theoperational capabilities of younger age group subjects, and aregenerally of such a nature as to effectively preclude easy and efficientindividual utilization thereof and inexpensive production of thevisually presentable media. The disadvantages of such systems have beenlong recognized. Attempts have been made in the past to overcome thesedisadvantages, and particularly the necessity of a darkened room forpresentation purposes, by provision of an automatic page-turningmechanism for visually presentable media that is synchronized withaurally reproduced sound. One such device, by way of example, isillustrated in United States Patent No. 2,323,628. Such devices,however, in so far as I am aware, have never been successful due, atleast in part, to a lack of sensitivity of the synchronizing systemsemployed, a lack of ready visibility of the visually presentable media,inherent limitations in the size of the visually presentable media dueto space or other limitations created by the structural arrangement ofthe page-turning mechanisms, a lack of means for effecting positivetimed displacement of the visually presented media, and expense factorsinvolved in the preparation of the visually presentable media utilizabletherein.

This invention may be briefly described as an improved construction foreffecting the automatically synchronized presentation of related visualmedia and aurally reproduced sound wherein such synchronization isautomatically effected by an inaudible signal previously introduced atpredetermined intervals in the stored sonal intelligence. Broadlyincluded therein is an improved construction for the mounting andpositioning of the visually presentable media in association with animproved page release indexing system to effect the synchronizedpresentation thereof that permits utilization of visual media of greatlyenlarged dimensions as well as the arrangement of such media in animproved book-like form that functionally cooperates with said mountingand positioning and page release indexing means to assure its selectivepresentation in a posi tive yet unobtrusive manner. Also included withinthe scope of the invention is an improved constructional configurationfor the individual pages of the book-like arrangement that permits itsdirect utilization for visual media presentation or its utilization as areusable selective support for separately prepared media on readilyremovable and inexpensive overlays to effectively remove any materialeconomic limitations in the preparation and fabrication thereof.

Among the advantages of the herein disclosed invention is the provisionof an improved, inexpensive, compact, self-contained and readilyportable construction for effecting the automatic synchronizedpresentation of related visual media and aurally reproduced sound thatfeatures an extreme simplicity of operation, a capability for extendedoperation on a day-to-day basis, and the permitted economicalpreparation of both the aurally reproducible sound and the visuallypresentable media by a user thereof in any desired quantity and with anydesired degree of detail or elaboration. Other advantages include apermitted Wide versatility of intended use, a permitted utilization ofgreatly enlarged visually presentable media that is capable of beingviewed by large groups without requiring room darkening or auxiliaryscreens, and a ready adaptability to varying systems for the productionof aurally reproduced sound. Still other advantages include an improvedconstructional arrangement and configuration for the individual pages ofthe book-like arrangement that permits direct imposition of the visuallypresentable media thereon or utilization thereof as a reusable supportfor an overlay of separately prepared visually presentable media andthereby affords such appreciable economies in the fabrication of suchmedia as to permit inexpensive utilization thereof even in extremelylimited quantities.

The object of this invention is the provision of an im proved and novelconstruction for effecting the automatic synchronized presentation ofvisual media with related aurally reproduced sound.

By way of general introduction and with reference to the schematicshowing of FIGURE 1 of the drawings, the multisensory intelligencetranmission device forming the subject matter of the herein disclosedinvention broadly includes means for effecting the aural reproductionand controlled amplification of pre-prepared and stored sonalintelligence, as generally illustrated at A; a control circuit means forsensing aurally inaudible electrical synchronizing signals preintroducedand integrally con tained at predetermined selective intervals in thestored sonal intelligence and providing a synchronizing output signal inresponse thereto, generally illustrated at B; and means responsive tosaid synchronizing signal output of said control circuit means forautomatically effecting the selective displacement of individual pagesof pre-prepared visual media in predetermined relation with the aurallyreproduced sound, as generally illustrated at C.

As there shown, the means for effecting the aural reproduction andcontrolled amplification of the stored sonal intelligence may suitablybe a phonograph having an integral and internally disposed audioamplifier means driving a loudspeaker 12 for aurally reproducing sonalintelligence stored on a phonograph record 14 or may be, with equalfacility, a tape playback unit 16 having integral and internallydisposed audio amplifier means driving a loudspeaker 18, for aurallyreproducing sonal intelligence stored on a tape.

Automatic operation is effected by the pre-introduction, atpredetermined desired intervals, of an aurally inaudible electricalpulse into the stored sonal intelligence, suitably a 30 cycle pulse ofsine wave form, as, schematically illustrated at 20, of such durationand amplitude as to permit selective sensing thereof by the controlcircuit means 22 to provide the desired synchronizing control functionas hereinafter described. The control circuit means 22 is adapted toselectively sense said pulse 20 and provide a complemental output signalof sufficient strength to initiate actuation of the Visual mediadisplacement means.

The visual media displacement means, as schematically illustrated at C,broadly includes a visual media mounting means, generally designated 24,arranged to hold and properly position a particularly bound booklikearrangement of a plurality of pages 26 of visually presentable media ina substantially vertical plane and in slightly bowed condition and acooperatively associated page release indexing mechanism, generallydesignated 28, adapted to selectively release the lead and exposed pagebearing or supporting the visually presentable media upon actuationthereof by the synchronizing signal output of t e Control circuit mean22, which released page of visually presentable media is pivotally andpositively displaced about its dependent binding edge to at least asubstantially horizontal position, thereby removing the heretoforeexposed visual media from the view of an observer and concomitantlyuncovering the visually presentable media on the now exposed and nextsucceeding page thereof. As will be apparent to those skilled in thisart, the visual media displacement means is of appreciable utilityirrespective of whether or not it is incorporated with a self-containedunit for aurally reproducing sonic intelligence.

The invention and the principles underlying the same will now be morespecifically illustrated and described in conjunction with certainpresently preferred embodiments thereof.

As illustrated in FIGURES 2 and 3, a preferred embodiment of theinvention is provided in the form of a compact, self-contained portableunit incorporating, by way of illustrative example, a phonograph foreffecting the aural reproduction of the sonal intelligence desired to betransmitted. There is provided a rectangular case 30 formed of a bottomor base portion 32 and a pivotally displaceable cover portion 64, whichas will be explained at a later point in the specification, serves tomount and position the visually presentable media as well as house thepage release indexing assembly. The bottom or base portion 32 isgenerally in theform of a rectangular box sized to contain, in theillustrated embodiment, a complete sound reproduction system including amotor operated turntable 34 and pivotally displaceable pickup arm 36mounted on the upper surface 35 thereof, and with the control circuitmeans 22 and a self-contained audio amplifier and loudspeaker locatedtherewithin and disposed behind the front panel'38. Manually operableexposed control knobs 40 are conventionally provided for startstop,volume and tone control purposes. Such a unit preferably includes a jack42 to selectively permit individual earphone utilization in lieu of thespeaker for private tutoring purposes, a second jack 44 to accommodateselective utilization of a tape playback unit in lieu of the phonographand in conjunction with the selfcontained control circuit means, audioamplifier and speaker for situations where the stored sonal intelligenceis on a tape rather than a record and readily accessible control button46 to afford a manual overriding control for actuation of the pagerelease indexing mechanism in accordance with the desires of a user, asfor example where the sonal intelligence is being orally delivered andwherein the visually presentable media is to be presented in accordancewith the orators pace of delivery. A suitable electrical circuit foraffording the above described flexibility of use will be later describedby way of specific example.

Peripherally mounted on the bordering edges of the upper surface 35 ofthe base portion 32 are a pair of vertically disposed auxiliary partialside wall portions 48, 50 and a rear wallportion 52 forming a generallyU-shaped enclosure for the turntable 34 and pickup arm 36 mountedthereon. The above described U-shaped enclosure 'is partially covered bya horizontally disposed visual media support plate or member 54, whichtogether with the extending exposed and coplanar edge portions 56, 58 ofthe side wall portions 48 and 50, respectively, functions to support thereleased pages of the visually presentable media 26 in a substantiallyhorizontal position and effectively out of the line of view of anobserver thereof. The support plate or member 54 is suitably spaced fromthe surface 35 so as to readily permit manual record mounting on theturntable 34 and pickup arm location thereon.

Although the specific unit illustrated in the drawings incorporates aself-contained phonograph for the aural reproduction of the sonalintelligence, at least equal, if not greater, utility would be affordedby the inclusion of a tape recorder or tape playback unit in lieuthereof.

Utilization of a tape unit in lieu of the illustrated phonograph wouldprobably afford a further diminution of size and weight, particularly ifa transistorized unit was employed, as well as providing a unit whereinthe stored sonal intelligence could be individually prepared by a userthereof.

Pivotally connected to the upper edge of the rear wall portion 52 as byhinges 6t) and 62 is the cover member 64 forming a part of the housingfor the unit, as illustrated in its open position. The cover member 64is shaped to provide a terminal end portion 66 of appreciably increaseddepth with a coverplate 67 disposed thereover for housing the pagerelease indexing assembly and is generally shaped and sized to becomplementally received, when in its closed position, in abuttingrelation by the front section of the base portion 32 to form a compactand readily portable closed unit of unbroken external configuration andof pleasing appearance. Suitably located snap fasteners 68 are desirablyprovided to secure the cover member 64 in its closed position to thebase portion 32.

In the illustrated embodiment, the inner surface of the cover member 64is provided with a transversely disposed metal mounting strip 70 alongand closely adjacent to the hinged lower edge thereof having its exposedsurface disposed substantially flush with the rear edge of the mediasupport plate 54 when said cover member 64 is in its open position. Themounting strip 70 is provided with a visual media mounting means in theform of a plurality of selectively located keyhole shaped apertures 72,74 complementally engageable by selectively shaped mounting means on thebinding edge of a booklike assemblage of pages visually presentablemedia, as will hereinafter be described, to support and properlyposition the same relative to the page release indexing assembly.

It is necessary to secure the cover member in the vertical plane and inperpendicular relation to the support plate 54 for proper operation and,in the illustrated embodiment, this is effected by manually displaceablebacking or spine member 76. The dependent edge of said spine member 76(see FIGURE 3) is preferably slightly tapered and is sized to passthrough an aperture 78 in the hinged edge of the cover member 64 and bereceived, in closely fitting relationship, within a receptacle member 80externally mounted on the rear wall 52 of the base 32. As shown inFIGURES 2 and 3, said spine member 76 is slideably contained within agenerally U-shaped slotted housing member 82 secured to the innersurface of the cover member 64. Displacement of said spine member 76 iseffected by manual operation of a lineally extendable and longitudinallyand rotationally displaceable knob assembly 84 connected to said spinemember 76 through a longitudinally disposed slot 86 in said housingmember 82. As best shown in FIGURES 4 and 5, the knob assembly 84includes a bolt member 87 perpendicularly secured to the spine member 76and sized to extend through the slot 86 in the housing member 82.Threadedly mounted on the extending end of the bolt member 87 anddisposed in adjacent abutting relation with the outer surface of thehousing member 82 is a cylindrical sleeve 88 having a generally E-shapedkeyway 89 recessed in the surface thereof. The E-shaped keyway 89includes an elongate longitudinally disposed track 90, a pair ofrelatively short terminally disposed transverse tracks 92 and 94 and anintermediate transversely disposed track 96. Mounted on the sleeve 88,and displaceably secured thereto as by a set screw 98 sized to have itsdependent end ride in said keyway 89, is a knurled knob member 100,preferably having a rubber covered end 102.

As illustrated, the spine or backing member 76 is verticallydisplaceable within the housing member 82. When the spine member 76 isdisposed at its upper limit of dis placement, as determined by theengagement of the bolt 87 wit h the upper end of the slot 86, thedependent end thereof will be contained entirely within the cover 64,thus permitting pivotal displacement thereof for opening and closingpurposes. When the spine member 76 is disposed at its lower limit ofdisplacement as determined by the engagement of the bolt 87 with thedependent end of the slot 86, the dependent end of the spine member 76will be disposed within the receptacle 8t) and the cover will be rigidlysecured in its vertical open position. The illustrated knob assemblypermits a locking of the spine member 76 at its upper and lowerpositions as well as additionally functioning to properly position thevisually presentable media, as will be explained hereinafter. Thelocking action is readily effected by rotative displacement of thesleeve 88 by manual rotative displacement of the knurled knob 106.Because of the threaded engagement of the sleeve 88 on the bolt 87,rotative displacement thereof results in a concomitant linealdisplacement along the longitudinal axis of the bolt 87 and in apermitted compressive engagement of the portions of the housing 82bordering the slot 86 intermediate a washer 91 disposed adjacent the endof said sleeve 88 and the surface of the spine member 76.

When the cover member 64 is disposed in its open posi tion bydisposition of the dependent end of the spine member 76 in thereceptacle and locked in such position by the above described rotativedisplacement of the sleeve 88, the knob 100 is disposed at a properelevation intermediate the mounting strip 70 and the page releaseindexing assembly in the terminal end 66 of the cover 64 tocooperatively function therewith to effect visual media displacement.Selective positioning of the knob 100 in the direction perpendicular tothe plane of the cover member 64 is effected by longitudinaldisplacement thereof relative to said sleeve 88. The proper positioningthereof is effected by introduction of the dependent end of the setscrew 98 into either the intermediate transverse track 96 or thetransverse terminal track 92. When so located in the intermediate track96, the knob 100 will be properly positioned to effect the desiredbowing of a properly mounted booklike arrangement of visuallypresentable media sized to be releasably indexed by the page releaseindexing means illustrated in FIGURES 3, 6 and 7. When so located in theterminal track 92, the knob 100 will be properly positioned to effectthe desired bowing of a properly mounted booklike arrangement ofvisually presentable media of further enlarged size that is adapted tobe releasably indexed by the auxiliary page release indexing meansillustrated in FIGURES 17 and 18.

The page release indexing means serves to cooperatively function withthe heretofore described structures to properly position the visuallypresentable media as well as to efiect the selective release ofindividual elements thereof in response to the receipt of asynchronizing signal contained in the stored aural intelligence. :Inorder to serve the dual function of page retention and page re lease,the page releasing indexing means, in accordance with the principles ofthis invention, includes stylus means engageable with the upper marginaledge of the pages of the visually presentable media that arereciprocably dis placeable intermediate a pair of defined limitingpositions, conveniently designatable as the first and second indexingpositions. Although such reciprocating stylii displacement can beeffected in numerous Ways as by utilization of solenoids or motoroperated earns, the hereinafter described construction constitutes apresently preferred embodiment that affords an accurate definition ofthe first and second indexing positions by utilization of inexpensivecomponents.

FIGURES 6 and 7 illustrate the constructional details of such presentlypreferred embodiment of a page release indexing assembly sized to behoused within the terminal end portion 66 of the cover member 64. Asshown, there is provided a base plate adapted to be fixedly secured tothe cover member 64. Mounted on the base plate 120 is a small DC. motor122 having a drive gear 124 secured to the drive shaft thereof. Thedrive gear 124 engages an idler gear 126 mounted on an auxiliary shaft128 that is rotatably supported by a pair of spaced standards 130, 132.Mounted on the forward end of the auxiliary shaft 128 and disposed indriving engagement with a horizontally displaceable rack 134, is a drivepinion 136. The rack 134 is mounted on the upper surface of a supportmember 138 having a pair of aligned horizontally disposed rods 140, 142extending outwardly from the ends thereof. The rods 140, 142 areslideably supported by a pair of selectively located supportingstandards 144, 146 mounted near the ends of said base plate 120. Mountedat the ends of the rods 140, 142 are a pair of connector members 148,150, respectively. Dependent from the connector members 148 and 150 area pair of spaced rodlike indexing stylii 152, 154 preferably havingsmall roller bearings 156, 158 mounted on the aligned and coplanardependent ends thereof. Preferably, the inner races of the rollerbearings 156, 158 are tightly press-fit onto the dependent ends of thestylii 152, 154 and the exposed outer races thereof are thus renderedfreely rotatable. As illustrated in FIGURES 2 and 3, the stylii 152, 154extend downwardly through suitable elongate slots in the underside ofthe housing cover member 67 and are disposed forwardly of the mountingstrip 70. Perpendicula'rly mounted on the base member 138 adjacent oneend of the rack 134 is a vertically disposed switch actuating post 162.As illustrated, the upper end of the post 162 preferably extends throughan elongate slot in an L-shaped guide plate 166 and has a small rollerbearing 164 mounted on the end thereof and running on said guide platefor antifriction alignment purposes.

Horizontal reciprocation of the rack 134 and concomitant linealdisplacement of the dependent rods 152 and 154 having the rollerbearings 156, 158 mounted on the dependent end thereof is readilyeffected by selective control of the direction and duration of rotationof the motor 122.

Rotative displacement of said motor shaft is transmitted through thedrive gear 124, the idler gear 126 and pinion 128 and is translated intolineal displacement of the rack 134 and rack base 138. Control of thedirection and duration of rotation of the drive motor 122 andconcomitant limitation of the length of the path of reciprocation of therack 134 defining the first and second stylii indexing position iseifected by selective switch actuation by the vertically disposed switchactuating post 162 in cooperation with the abutting engagement of thesupport member 138 with the standards 144, 146. As illustrated, theswitch actuating post 162 is positioned to engage an extended switchactuating arm 170 during horizontal displacement of the rack 134 in onedirection to open normally closed electrical switch 172, and to engage asecond extended switch actuating arm 174 during horizontal displacementin the other direction to open a second normally closed electricalswitch 176. By properly locating the depending stylii 152, 154 relativeto the center line of the mounted visual media and by effectivelycontrolling the limiting or indexing positions thereof relative to saidcenter line, as in the illustrated construction, complemental indexingrecesses may be readily and selectively prelocated in the marginal edgeof visual media so as to permit utilization of both surfaces thereof bymere reversal of the hereinafter described booklike arrangement thereof.As will be explained immediately hereinbelow, the selective opening ofthe switches 172 and 176 which takes place when the ends of the supportmember 138 are closely adjacent to the standards 144, 146 serves to openthe circuit for the motor 122 and halt its operation with any overtravelof the rack assembly being limited by the standards 144, 146 therebypositively defining the limits of rack and stylii displacement and thelocations of said first and second indexing positions.

FIGURE 8 illustrates, by way of example, a suitable control circuit forcontrolling the direction and duration of operation of the DC. motor 122and to thereby effectively control the direction and limits ofreciprocating displacement of the rack 134 and the indexing styliiassociated therewith. There is provided a source 200 of relatively lowDC. voltage, conveniently the rectified output of the low voltagefilament transformer for the audio amplifier means disposed in the soundreproducing unit. The terminals of the voltage source 200 are directlyconnected to the movable armatures 202, 204 of a latching relay ofconventional construction. Such movable armatures 202, 204, as isconventional in latching relays, are adapted to be displaced in unisonupon energization of the latching relay energizing coil and, after suchdisplacement, to remain latched in their displaced condition until thenext subsequent energization of the latching relay energizing coileffects a delatching and return thereof to their initial latchedposition. As illustrated, the armature 202 is displaceable intermediatefirst and second relay contacts 206 and 208 and the armature 204 isdisplaceable intermediate third and fourth relay contacts 21.0 and 212.As mentioned above, the armatures 202, 204 are adapted to be displacedin unison upon energization of the latching relay energizing coil andare so arranged as to be in selective simultaneous contact with thecontacts 208, 212 (as illustrated) or in selective simultaneous contactwith the contacts 206, 210. The first relay contact 206 is connected bymeans of a lead 214 to one input terminal 216 of the DC. motor 122. Thesecond relay contact 208 is connected through the nor-mally closedswitch 172 by means of a lead 218 to the second input terminal 220 ofsaid motor 122. The third relay contact 210 is connected through thenormally closed switch 176 by means of a lead 222 to the second motorterminal 220. The fourth relay contact 212 is directly connected as by alead 224 to the first motor terminal 216.

In operation of the above circuit, a suitable D.C. potential iscontinuously applied across the input terminals 200 and is thuscontinuously present across the movable armatures 202, 204 of thelatching relay. With the armatures positioned as illustrated, the drivecircuit for the motor 122 is effected through relay contact 208,normally closed switch 172, lead 218, through the motor 122 and returnsthrough the lead 224, the relay contact 212 and armature 204. Thedirection of the current flow through the motor 122 will effectselective rotation thereof in one direction and will initiate linealdisplacement of the rack 134 from one limiting position towards theother, for example towards switch actuating arm 170. The linealdisplacement of the rack 134 will continue until the switch actuatingpost 162 engages the extended actuating arm 170 and effects an openingof the switch 172. Upon the opening of the switch 172, the heretoforedescribed motor circuit will be opened and motor operation will behalted and the depending stylii 152, 154 will be disposed at theirlimiting or indexing position in abutting relation with the standard146. Such stylii positioning will be maintained until the energizingcoil for the latching relay is again energized, as effected by thesensing of a synchronizing signal through the control circuit means 22or by depression of the manual control button 46. Upon such energizationof the latching relay, the armatures 202, 204 will be transferred inunison into electrical engagement with relay contacts 206 and 210,respectively, and will be latched in such position. A motor circuit isthus again completed through the armature 202, relay contact 206, lead214, motor 122, lead 222, normally closed switch 176, relay contact 210and armature 204. With the armatures 202, 204 so located, the currentflow through the motor 122 is in the opposite direction from thatheretofore described and the motor will reverse its direction ofrotation. The reversal of the direction of the motor operation effects alineal displacement of the rack 134 and dependent stylii 152, 154 fromthe heretofore described limiting position and in the direction oppositethat heretofore described. The initiation of such movement will resultin a disengagement of the post 162 from the arm 170 and in an automaticclosure of the previously opened switch 172. Lineal displacement of thestylii 152, 154 will so continue until the switch actuating post 162engages the switch actuating arm 174 and opens the normally closedswitch 176. The opening of the switch 176 will open the motor circuitand halt motor operation. At the point of cessation of motor operationthe support member 138 will be positioned closely adjacent the standard174 and any overtravel will be limited by engagement therewith topositively dispose the stylii in their other limiting position. Thestylii 152, 154 will remain in such limiting or indexing position untilthe latching relay is again energized in response to the receipt of asynchronizing signal 22.

As will be apparent to those skilled in the art, the above describedsystem or motor operation will effect a reciprocating displacement ofthe dependent stylii 152 and 154 intermediate defined first and secondindexing positions which are spaced a predetermined distance apart andin predetermined uniform relation to the center line of the mountedvisual media, and that displacement thereof intermediate the first andsecond indexing positions is effected by each energization of thelatching relay energizing coil in response to the recepit of asynchronizing signal 22 or the manual actuation of the control button46.

FIGURE 9 illustrates, in block diagram form, suitable electrical circuitarrangements for the internally contained audio amplifier means andcontrol circuit means 22. As there illustrated, the output of thephonograph pickup assembly 230 is fed through a normally closed switch232 into a two-stage audio amplifier 234 of conventional construction.The output of the audio amplifier 234 is conventionally coupled to aloudspeaker 236 through a coupling transformer 238 and a normally closedswitch 240.

The switch 232 is so arranged as to be opened by insertion of a plugmember into the jack 44 (see FIGURE 2) to automatically disconnect thephonograph pickup 230 and connect a tape unit to the audio amplifier 234in lieu thereof and thereby permit selective utilization of a tapeplayback unit as a source of the aurally reproducible intelligence inlieu of the illustrated phonograph pickup unit 230.

The switch 240 in the speaker circuit is similarly arranged with respectto the jack 42, so as to effect automatic disconnection of theloudspeaker 236 upon insertion of an earphone plug into said jack 42 tothereby selectively receive the output of the audio amplifier 234 insaid earphones and permit utilization of the device by an individual, asfor example, as a private tutor without disturbing others in thevicinity thereof.

The control circuit means 22 suitably includes a frequency selectiveamplifier 242 of essentially conventional construction having its inputterminal preferably con nected to the output of the first stage of thetwo-stage audio amplifier 234. As will be explained in more detailhereinafter, the frequency selection amplifier 242 is suitably of thetype that includes a parallel T null network in the feedback loop toselectively feed back all frequencies other than the frequency of thesynchronizing signal and thereby effect cancellation thereof. The outputof the frequency selective amplifier 242, which is essentially arelatively pure amplified 3O cycle pulse is fed into a rectifier 246 andthe rectified output thereof is utilized to trigger a normallynon-conducting relay switching tube 248 into conducting condition. Anenergizing control coil for the heretofore described latching relaymeans is suitably disposed in the plate circuit of the relay switchingtube 248 and is arranged to be energized whenever said tube 248 isplaced in a conducting position.

FIGURE 10 is illustrative of a suitable circuit arrangement for theelements includable in a control circuit means 22 to effect the desiredactuation of the heretofore described latching relay in response to thesensing of each inaudible 3O cycle synchronizing signal preintroducedinto the stored sonic intelligence. As there shown, the input, which ispreferably obtained from the output side of the first amplifier stage ofthe two-stage audio amplifier 234, is applied through a couplingcondenser 260 to the control grid 266 of an amplifier tube 268. Thecapacitor 262 and resistor 264 disposed in the grid circuit thereof forman R-C filter network to effect an initial and partial attenuation offrequencies other than that of the synchronizing pulse, i.e. the 30cycle pulse. The output of the amplifier 268 is fed through a second R-Cfilter formed of capacitor 270 and resistor 272 to effect a furtherpartial attenuation of frequencies other than that employed for thesynchronizing signal and is applied to the control grid 274 of thefrequency selector amplifier tube 276. The cathode 275 of said tube 276is suitably biased by a voltage divider network that includes resistors278, 280 and the plate load resistor 282 of the pro-amplifier stage 268connected intermediate the plate supply voltage and ground. The grid 274is connected to ground through a suitable grid bias resistor 284. Theoutput of the frequency amplifier tube 276 passes through a couplingcondenser 286 and is applied to the grid 288 of a voltage amplifier tube290. Connected intermediate the grids 274 and 288 of the frequencyselective amplifier tube 276 and voltage amplifier tube 290,respectively, is a parallel T null network formed of resistors 292, 294,296 and capacitors 298, 300 and 302. The illustrated parallel T nullnetwork is thus included in the feed-back loop for the tube 275 and thecircuit constants thereof are chosen to selectively feed backfrequencies other than the 30 cycle synchronizing signal and to thusactively cancel the same on the grid 274. The amplified wave form thatthus appears on the grid 288 of the voltage amplifier tube 290 istherefore essentially a pure 30 cycle signal. The cathode of the voltageamplifier tube 290 is suitably biased by means of a connection to avoltage divider network formed of fixed resistors 304 and 308 andadjustable resistor 306.

The amplified 30 cycle signal output of the amplifier tube 290, which ispresent only when a synchronizing signal is sensed, is applied to thecathode 310 of a rectifier 312 through a coupling condenser 314. Therectified DC. output of the rectifier tube 312 is a positive pulse ofDC. voltage.

The energizing control coil 316 for the heretofore described latchingrelay means is disposed in the plate circuit of a relay switching tube318. The relay switching tube 318 is normally biased beyond cut-off bythe presence of a negative rectified DC. voltage obtained byrectification of 60 cycle voltage in the rectifier tube 320. Asillustrated, the rectifier tube 320 has its cathode 322 connected to asource of alternating voltage. The negative rectified output thereofappears on the grid 324 of the relay switching tube 318 and is of suchmagnitude as to normally bias said tube 318 beyond cut-off. When thepositive voltage resulting from the rectified 30 cycle pulse appearsacross resistor 315 it is in opposition to the negative DC. output ofthe rectifier tube 320 and effectively raises the voltage on the grid324 of the relay switching tube 318 beyond cut-off and initiatesconduction thereof. As illustrated, the grid 324 is connected to an R-Ccircuit formed of resistor 326 and capacitor 328 and a slightly extendedperiod of conduction of tube 318 is effected by the charging of saidcondenser 328 so as to assure a sufiicient duration of control relaycoil energization to permit latching relay armature displacement. Whenthe relay switching tube 318 conducts, current flows through theenergizing control coil 316 for the latching relay, energizing the sameand effecting a displacement of the latched armatures 202 and 204(FIGURE 8) from one set of contacts to the other.

The manually operable switch 46 is connected in series with a limitingresistor 317 intermediate the plate supply voltage and the grid 324 ofthe relay switching tube 318, which as indicated above, is normallybiased beyond cutoff. Closure of the switch 46 results in raising thevoltage on the grid 324 and in conduction of tube 318 with consequentenergization of the latching relay.

As will be apparent to those skilled in this art, the action of theabove described circuit is such as to sense and effect a selectiveamplification of the 30 cycle synchronizing signal incorporated in thestored intelligence and to provide a synchronized output signal ofsufficient strength and duration to effect energization of the latchingrelay and consequent displacement of styli 152, 154 from one indexingposition to the other, as described above.

FIGURE 11 illustrates the preferred constructional configuration andarrangement for the individual pages 350, 350a, 3501) etc. of thebooklike arrangement upon which the visual media is directly presentedor supported. As illustrated, each page 350 is rectangular in shape withthe longer dimension running in the direction of the arrows 354 and isformed of relatively heavy index type paper stock. or of relativelyheavy card stock. Such material should be formed to have a strong grainrunning in vertical direction, i.e. as indicated by the arrows 352, togive the individual pages a considerable amount of inherent resiliencewith the amount thereof desired varying in accordance with the size ofthe page. The paper stock surface is preferably coated with plastic orvarnish so as to provide a smooth hard surface to prevent or at leastminimize moisture absorption and to maintain its inherent resilienceunder varying climatic conditions. A suitable paper stock is the RegalPaper Companys Tuff- Wite in 150 lb. or heavier weight and formed, asdescribed above, with a strong grain running in the direction indicatedby the arrows 352.

The individual pages 350 are formed with a plurality of uniformly spacedbinder receiving perforations 356 along the marginal binding edge 358thereof. The side edges 360, 362 are provided with small rectangularrecesses 364, 366 spaced inwardly a predetermined uniform distance fromsaid marginal binding edge 358. The upper edges 368 are provided with apair of selectively spaced and sized rectangularly shaped indexingrecesses 370, 372. The indexing recesses 370, 372 are spaced apart adistance equal to the spacing of the indexing stylii 152, 154 and arelocated relative to the vertical center line of the page so as to be inautomatic alignment with either the first and second indexing positionsof said stylii dependent upon which planar surface thereof is in theforward facing position. This permits all the pages to be die cut in oneoperation and proper arrangement thereof effected for indexing purposesby alternate page reversal thereof. As illustrated, the individual pagesare arranged so that the indexing recesses 370, 372 on the first page350 are disposed in alignment with one of the limiting positions of thestylii 152, 154, for example, the first indexing position thereof. Therecesses 370a and 372a on the second page 350a are disposed in alignmentwith the other limiting position of the stylii for example, the secondindexing position thereof, by mere page reversal as described above. Therecesses 370i) and 372b on the third page 3501) are disposed inalignment with the recesses on the first page 350 and so forth. As willbe now apparent, the above construction permits all pages to be preparedby a single die cutting operation and yet permits utilization of bothsides of each page for the presentation of visual media in propersequence by mere reversal of the mounting of the assemblage thereof.

An assemblage of pages as illustrated in FIGURE 11 and arranged asdescribed above are mounted on a rigid backing or mounting member in thegeneral form of a ringbinder, as illustrated in FIGURES 12 and 13, toform a booklike arrangement thereof for the sequential presentation ofvisual media. As there illustrated, the mounting .member includes aplurality of substantially circular mounting rings 380 sized to freelypass through the perforations 356 disposed along the marginal edge 358of the pages 350 and to thereby form an essentially continuous rigidsupport for the marginal binding edge thereof which prevents anyundesired twisting or bending thereof that could adversely affect thepage release indexing operation. The rings 380 are mounted on a rigidbacking strip 382 and preferably are of such nature as to be openable,as per, for example, the conventional loose leaf binder assemblies, topermit page collation and selective page arrangement by the ultimateuser thereof. The rear of the backing strip 382 contains selectivelylocated integral mounting means complementally engageable with theselectively located mounting means on the mounting strip 70 secured tothe lower edge of the heretofore described cover member 64 to firmlysecure the marginal edge of said booklike assemblage to the cover memberand to automatically properly position the indexing recesses 370, 372etc. of the sequentially arranged pages thereof relative to the firstand second indexing positions of the stylii 152, 154. In the particularillustrated example, the mounting means on the mounting strip 70 (FIGURE2) consists of the selectively shaped keyholelike apertures 72, 74. Thecomplemental mounting means on the back of the backing strip 382 are inthe form of a pair of studs or pins 384 having an annular recess 386therein sized to be received within the reduced size portion of thekeyhole-like apertures 72, 74 and thereby permit easy inserting andremoval of the booklike arrangement of visually presentable media and afirm and secure mounting thereof in proper positional relationship withthe indexing stylii for operational purposes. If desired the pins 384could be mounted on the strip 70 and the keyhole apertures included inthe body strip 382.

A complete sequence of operations will now be described. A unit such asillustrated in FIGURES 2 and 3 is placed upon a suitable horizontalsurface and plugged into a convenient source of electrical power. Thecover member 64 is pivotally displaced into its open position asillustrated in FIGURE 2 and locked in such position by displacement ofthe dependent end of the spine member 76 into the receptacle 80 andlocking said spine 76 as so positioned by rotative displacement of theknob assembly 84. The knob is then extended and positioned by thedisposition of the dependent end of the set screw 98 in the intermediatetransverse track 96 in the keyway '89.

A pre-prepared booklike arrangement of pages 350 is there mounted byintroducing the pins or studs 384 on the back of the backing strip 382into the keyhole-like apertures 72, 74 in the muonting strip 70 in suchman ner as to locate the annular recesses 386 in the reduced sizeportions of the keyhole apertures 72, 74. The book of visual media isthen pivotally displaced about its now secured binding edge and theupper marginal edge 368 is placed behind the dependent stylii 152, 154,which should be located at the indexing position disposed remote fromthe indexing recesses 370, 372 on the first or exposed media page 350.Stylii positioning for loading operation can be readliy effected bymanual operation of the button 46. As best shown in FIGURE 3, a properlypositioned book of visually presentable media is securely positionedalong its marginal binding edge, has its upper marginal edge disposedbehind the dependent indexing stylii and is releasably retained at atleast two separated locations thereby, and is deformed so as to beforwardly bowed or biased for falling pivotal displacement by theextended knob member 100 disposed in compressive engagement against therear of the mounted book substantially centrally thereof.

With the book of visually presentable media so positioned, a record 14containing the aurally reproducible sonal intelligence and thepro-introduced synchronizing signals is placed on the turntable 34,turntable rotation started, and the pick-up arm 36 located at the startthereof. From here on operations are entirely automatic. As the auralintelligence is sonically reproduced, the lead or exposed page 350 ofthe visually presented media will remain in view of the observersthereof. Upon receipt of the first inaudible synchronizing signal, theindexing stylii 152, 154 will be lineally displaced towards the indexingrecesses 370, 372 on the exposed media page. When these stylii reachtheir indexing position, for example, the first indexing position, theywill be disposed within the recesses 370, 372 of said first page, out ofretaining engagement therewith and in retaining engagement with themarginal edge portion 368 of the next succeeding page. Upon the releaseof stylii engagement with the lead page, the inherent resilience thereoftends to cause it to reassume a planar condition. However, since suchpage is secured along its mounting or binding edge and is subjected to apressure by the knob 100 adjacent its center, the inherent resiliencethereof is translated into an initial rapid pivotal displacement thereofabout its marginal bound edge towards the horizontal position on thesupport plate 54 and rapid removal thereof from the view of an observerand concomitant rapid exposure of the visually presented media on thesucceeding and now exposed page being retained by the stylii 152, 154.Such operation is repeated upon the recepit of each synchronizing signalcontained in the stored sonal intelligence until all the pages in thebook of media have been displaced into the horizontal position. Uponcompletion the production may be rerun or the book may be removed,reversed and replaced and the record reversed to utilize the heretoforeunused obverse sides of both the visual and audio intelligence storageunits.

The above described system provides for the disposition of greatlyincreased amounts of transmittable intelligence in a single visual-auralrecord and book combination as well as a permitted use of large sizevisually presentable media. In the illustrative embodiment there iseffectively no Width limitation in the size of the media page. This,coupled with the above described visual media mounting and positioningmeans, has readily permitted use of visual media 14 by 18 inches insize.

Although the above described paper stock for the pages 350 can readilyhave the visually presentable media printed or otherwise directlyapplied or imposed thereon, economic and other considerations will oftendictate the utilization of such pages 350 as a reusable support for thevisually presentable media. To this end the herein disclosed inventionincludes the utilization of specially contoured overlays that arereadily mountable on and removable from the individual pages 350. Suchoverlays can be made of much lighter paper stock, can be printed bycontinuous printing or other varied reproduction methods in largequantities and can also be formed of special papers, such as thediazotype, that are suitable for low cost reproduction of line and halftone illustrations. Apart from the material economic savings inherent inthe utilization of such overlays to the ultimate users thereof, suchoverlays also provide an extreme flexibility of use to the ultimate userby enabling him to selectively and economically prepare his own visualmedia in quantities as low as a single copy thereof. To this end thereis provided, as illustrated in FIGURES 14 and 16, a specially contouredoverlay 390. The overlay 390 is in the form of a folded sheet having thehalves thereof of equal size and provided with an elongate cutoutportionin the form of a rectangular recess 392 in the folded edgethereof and defining terminally disposed folded portions 394, 396. Asbest shown in FIGURE 16, the overlay 390 is slipped over the page 350and supported thereon by the abutting overlying relation of the foldedterminal ends 394, 396 of the overlay on the upper edge 368 of the page350. As illustrated, the overlay 390 is sized to be slightly smallerthan the page 350 so as to leave exposed marginal side edge portions398, 400 adjacent the side edges 362 and 360 of the page 350 and anexposed marginal edge 404 inwardly of the line of perforations 356.Although such overlay may be removably secured by known adhesives, toreadily facilitate prefrered securement and removal of the overlay 390without damage to the page 359, the overlay is sized so that the sideedges 406, 408 thereof are disposed in alignment with, or slightlyextend beyond the bases of the rectangular recesses 366, 364 in the page350. This permits to two pages of the folded overlay to be easily andreadily secured together by small U-shaped pieces of clear pressuresensitive cellophane tape 402 disposed within said recesses 364, 366 andthereby out of adhesive contact with the page 350. Such securement,coupled with supporting engagement of the terminal folds 394, 396 on theupper edge 368 of the page 350 prevents displacement of the overlay 390in any direction and yet is readily removable by a user, as by cuttingthe adhesive strip, without any damage to either the overlay 390 or tothe support page 350. As will be apparent, the elongate recess 392 issized to expose the indexing recesses 370, 372 011 the upper edge 368 ofthe page 350 and permit unimpeded displacement of the indexing stylii152, 154.

As shown in FIGURE 15, such folded overlay pages 390 may be convenientlypreassembled in pad form having a conventional glue binding 410 andsuitably perforated, as at 412, adjacent thereto for ready separationthereof. If desired, such pad can be provided with a relatively rigidbacking page 414 and a foldable cover 416 to protect any visual mediaas, for example, sketched thereon by a user. This arrangement of theoverlay pages 390 thus renders the same conveniently available ininexpensive form to a user thereof and greatly facilitates individualpreparation of the visually presentable media in single copies thereof.

FIGURES 17 and 18 are illustrative of an alternate and preferredconstruction for a page release indexing means adapted to be disposed inthe terminal end portion 66 of a cover member 64. The specificallyillustrated unit is of the type illustrated in FIGURE 2 butincorporating an additional set of stylii so as to enable such unit toconveniently handle books of visually presentable medie of furtherenlarged size. Common elements will bear the same reference numerals asheretofore employed.

As shown there are provided a pair of upright support members 450, 452mounted on the upper surface of the connector members 148, at the endsof the rods 140, 142, respectively.- Secured to the top of the supportmembers 450, 452 is a horizontally disposed plate member 454. Slideablymounted at each end of the plate member 454 and displaceablytransversely thereof are an auxiliary pair of indexing stylii 456, 458.As best shown in FIGURE 17, the stylii are of a generally L-shapedconfiguration having roller bearings 460, 462 mounted on the dependentends thereof and are slideably displaceable from an extended position,illustrated by the solid lines, to a retracted position as illustratedby the dotted lines. When in extended condition, as illustrated in FIG-URE 17, the stylii 456, 458 extend through a recessed rectangularaperture 464 in the cover plate 67. When the stylii 456, 458 aredisposed in their retnacted position, said aperture 464 is covered by adisplaceable cover member 466 hingedly connected as at 468 whicheffectively hides said stylii from the view of an observer.

By the above construction, it will be apparent that the lower ordependent stylii 152, 154, as described earlier in conjunction withFIGURES 2, 6 and 7, are always available for use with a booklikearrangement formed of pages of a given size as for example, 14 x 18". Ifpages of a larger size, for example, 18" x 24 are to be used, the coverplate 466 is open and biased in open position. The recessed stylii 456,458 are then manually extended to the advanced position as illustratedin FIGURE 17 and as such are readily available for use with pages 350 ofappropriate increased size. Preferably the auxiliary indexing stylii456, 458 are spaced further apart than the stylii 152 and 154, sinceimproved positioning of the larger size pages is obtained by a furtherseparation of the indexing stylii. Since the stylii 456, 458 are mountedon the connecting members 148, 150, they will move in unison therewithand will traverse, during their reciprocation a predetermined pathhaving predetermined limited or indexing positions as was describedabove in detail in conjunction with, the FIGURES 6 and 7 assembly. As isapparent the indexing recesses in the larger sizes of paper 350 will besuitably located to permit indexing and page releasing operations in thesame manner as that described in the earlier portions of thisspecification. The proper biasing of the mounted book for displacementto the horizontal plane is again effected by extension of the knob 100.When utilized in conjunction with the stylii 456, 458 said knob is movedto its extended position as determined by the disposition of thedependent end of the set screw 98 in the terminal transverse track 92.

FIGURE 19 schematically illustrates a suitable construction for a signalgenerator to generate a 30 cycle synchronizing signal and for effectingthe introduction thereof into stored sonic intelligence. As there shown,a continuously operable motor 480 running at a speed, for a 30 cyclesignal, of 1800 rpm, drives a slightly eccentric rotor 482. Theeccentric rotor 482 bears against a lever arm 484 which applies pressureto a piezo electric crystal generator 486. The piezo electric generator486 is connected in series with a button operated switch member 488, anda variable gain control resistor 490. The movable contact 492 of theresistor 490 is connected, through a resistor 494, to a terminal 496. Asonic input unit, for example a microphone 498, is also connected,through a resistor 500, to said terminal 496. The illustrated unit is,by way of example, particularly adapted for utilization with a singleinput tape recorder. The terminal 496 is adapted to be connected to theinput of the tape recorder and the desired aural intelligence isintroduced therein through the microphone 498. Whenever it is desired tointroduce a 30 cycle synchronizing signal into the stored intelligence,all that is required is to close the switch 488, since the piezoelectric generator is being periodically compressed by the action of themotor driven eccentric rotor 482 and lever 484. The resulting signal,upon closure of the switch 488, is a 30 cycle signal of essentially puresinewave configuration, which appears as the desired inaudiblesynchronizing signal in the resultant stored sonal intelligence.

FIGURES 20 and 21 illustrate possible additional complementalconfigurations for a page release indexing mechanism. As illustrated inFIGURE 20, a vertically displaceable T-shaped stylus 510 is provided andadapted for use with vertically staggered T-shaped indexing recesses514, 516 on sequentially arranged pages of visually presentable media.In operation of such a system, the T-shaped stylii will be verticallyreciprocated as indicated by the arrows 512 to effect the desired pageretention and page release indexing.

In the FIGURE 21 embodiment, an indexing stylus 528 is pivotally mountedas at 522 and adapted to be oscillated through a predetermined are, asindicated by the arrows 524. Complementally associated therewith areangularly disposed indexing recesses 526 and 528 alternately arranged onthe upper marginal edges of the successive pages of visually presentablemedia. In this embodiment, rotative displacement of the stylii 520through a predetermined arc intermediate first and second indexingpositions will result in the desired sequential release of the pages.

As will be apparent to those skilled in this art, the above describedstructures incorporating the principles of this invention have anextremely wide versatility of use and can be fabricated with aself-contained aural :sound reproduction unit or as a subassembly foreffecting the selective presentation of visual media in conjunction witha users own sound reproducing units such as a phonograph or taperecorder or tape playback unit.
